Abstract
The invention discloses a kind of to pull-type poured pile base pit supporting construction, be made up of soldier pile, steel mesh reinforcement and anchor pole, on the pile body horizontal level direction of soldier pile, be wherein distributed with the bolthole of more than 2 from top to bottom, and bolthole is all positioned on same vertical plane, the two ends of anchor pole are connected with soldier pile respectively, and steel mesh reinforcement is fixed on termination point of anchor rod.The present invention can be widely used in the foundation pit supporting construction of building field, particularly in the foundation pit supporting construction excavating geology historical relic scene, effectively can prevent the collapse body on foundation ditch side from collapsing, and can save a large amount of anchor pole materials, convenient construction.
Description
Technical field
The present invention relates to a kind of the realm of building construction, is a kind of to pull-type poured pile base pit supporting construction specifically.
Background technology
At present anchor-pull brace structure is all extensively adopted to carry out the protection of foundation ditch when the both sides excavation pit of the realm of building construction to collapse body, in the both sides of collapse body, soldier pile is set respectively, and respectively anchor pole oblique cutting is entered collapse body inside, one end of anchor pole is fixedly connected with soldier pile, on termination point of anchor rod, be fixed with steel mesh reinforcement simultaneously, can spray on steel mesh reinforcement during use and establish concrete.When collapse body collapses because of stressed, then can by this force transmission on soldier pile and steel mesh reinforcement, when this active force exceed supporting and steel mesh reinforcement bear power time then this firmly can be passed on termination point of anchor rod further, this active force is postponed on anchor pole by termination point of anchor rod again, by the friction of anchor pole and collapse body and then improve soldier pile and steel mesh reinforcement to the protective capacities of collapse body.Its protection effect of this supporting and protection structure is in principle by length and the quantity that then will depend on anchor pole, and its friction provided is also larger more at most for the quantity of the longer or anchor pole of rock-bolt length, and then soldier pile and steel mesh reinforcement can be made to bear larger pressure.Due to anchor pole carry out bilateral oblique to insert, if adopt increasing rock-bolt length to improve its friction, then there will be anchor pole intersection region in collapse body central authorities, anchor pole cost will certainly be increased, if improve its friction in the mode increasing anchor pole quantity and Multi anchorage effect can be produced because spacing is too little, by reduce anchor pole breakout capacity and increase displacement, be unfavorable for the protection to collapse body, there is serious potential safety hazard.And these 2 kinds of modes all can increase engineering quantity, and then increase construction costs, be unfavorable for creating conservation-minded society.
Summary of the invention
In order to solve the deficiency of prior art structure, the invention provides a kind of to pull-type poured pile base pit supporting construction, to reach saving cost, avoiding the generation of Multi anchorage effect, improve the object of the protective capacities to collapse body.
The present invention is realized by following technical proposals: in the supporting and protection structure be made up of soldier pile, steel mesh reinforcement and anchor pole, the pile body of soldier pile is provided with bolthole, the two ends of anchor pole are each passed through bolthole and are connected with castinplace pile, and steel mesh reinforcement is fixedly connected with on termination point of anchor rod, bolthole on every root soldier pile all distributes in horizontal level, its quantity is at least 2, and bolthole is all positioned on same vertical plane.During use, by the both sides of soldier pile vertical distribution in collapse body, and the bolthole of one end of anchor pole from a wherein soldier pile is passed, and pass from the bolthole of another root soldier pile of same level position, then with nut, anchor pole two ends are pinned, be fixed on by steel mesh reinforcement on the termination at anchor pole two ends, anchor pole, soldier pile, a formation entirety between steel mesh reinforcement and collapse body, can prevent collapse body from collapsing so simultaneously.
The invention has the beneficial effects as follows: not only to collapse body, there is very strong protective action, can be widely used in the construction field needing to carry out two-sided protection, and product structure is simple, can save a large amount of construction costs, easy construction, be convenient to promote the use of.

Code description in figure: 1,1 ' soldier pile; 2 anchor poles; 3 nuts; 4 steel mesh reinforcements; 5 collapse body; 6,6 ' soldier pile; 7 steel mesh reinforcements; 8 nuts; 9 boltholes.
Detailed description of the invention
As shown in Figure 1, the present invention is made up of soldier pile (1) (1 ') (6) (6 '), anchor pole (2), nut (3) and steel mesh reinforcement (4) (7), soldier pile is equipped with bolthole (9), and wherein the horizontal level of the upper bolthole of soldier pile (1) (1 ') is all corresponding, the horizontal level of the upper bolthole of soldier pile (6) (6 ') is all corresponding.In use as shown in Figure 2 and Figure 3, soldier pile (1) (1 ') (6) (6 ') is separately positioned on the both sides of collapse body (5), collapse body corresponding to bolthole is holed, then anchor pole (2) is pierced into from the bolthole soldier pile (1), and pass from the bolthole soldier pile (1 '), use nut (3) (8) to be pinned by anchor pole respectively at the two ends of anchor pole, respectively steel mesh reinforcement (4) (7) are fixed on termination point of anchor rod simultaneously, then order carries out concrete spray operation on steel mesh reinforcement, makes steel mesh reinforcement form one protection slab.After being fixed through adopting the present invention; collapse body and supporting and protection structure form an entirety; collapse body either party be subject to active force all by its supporting and protection structure by this force transmission on mass failure body, thus reach the object effectively preventing collapse body from collapsing, realize the good protection to foundation ditch.
It should be noted that, soldier pile is in the present invention equipped with 3 boltholes, but can carry out increasing or reducing according to the degree of depth of foundation ditch in actual use, but at least should keep 2 boltholes.Although the quantity of soldier pile is 4 groups in enforcement as shown in Figure 2, can carry out increasing and reducing according to actual conditions equally, but at least should retain 2 groups of soldier piles (namely 4) to form complex whole.
Be connected because anchor pole in the present invention is directly fixed with the soldier pile of both sides; thus the length of anchor pole is effectively shortened; significantly decrease the usage quantity of anchor pole simultaneously; save cost; give full play to the resistance to tension of single anchor pole; decrease the distortion of one-sided anchor structure, be more conducive to environmental protection.
Claims (1)
1. one kind to pull-type poured pile base pit supporting construction, be made up of soldier pile, steel mesh reinforcement and anchor pole, it is characterized in that: soldier pile is separately positioned on the both sides of collapse body, the pile body of soldier pile is provided with bolthole, the two ends of anchor pole are each passed through bolthole and are locked with castinplace pile by nut and are connected, and steel mesh reinforcement is fixedly connected with on termination point of anchor rod, steel mesh reinforcement is coated with layer of concrete, the all horizontal distribution of bolthole on every root soldier pile, its quantity is at least 2, and bolthole is all positioned on same vertical plane.
